Introduction
Rusted toilet tank bolts can be quite a hassle to deal with, but with the right approach and tools, you can remove them successfully. The process generally involves penetrating oil to loosen the rust and careful maneuvering to avoid damaging your toilet. Here’s a step-by-step guide to help you through the process.
Tools and Materials Needed
- Penetrating Oil (e.g., WD-40)
- Wrench or Socket Set
- Hacksaw or a Bolt Cutter (if necessary)
- Pliers or Vise Grips
- Cloth or Rag
- Safety Glasses
- Replacement Bolts and Washers
- Putty Knife or a Small Wire Brush (for cleaning)
Step 1: Turn Off the Water Supply
Before starting any work on your toilet tank, make sure to turn off the water supply to prevent any potential flooding. The shut-off valve is usually located on the wall behind the toilet. Turn it clockwise to close it. Once the water is off, flush the toilet to drain the tank completely.
Step 2: Apply Penetrating Oil
Spray the penetrating oil liberally on the rusted bolts. Ensure you wear safety glasses to protect your eyes from drips. Let the oil sit for at least 15-20 minutes, or even longer if the bolts are severely rusted. The oil helps to loosen the rust and make it easier to unscrew the bolts.
Step 3: Attempt to Loosen the Bolts
After allowing the oil to penetrate, use a wrench or socket set to attempt to loosen the bolts. Do this gently to avoid breaking the bolts or damaging the toilet. If the bolts won’t budge, apply more oil and wait a bit longer.
Step 4: Secure the Nuts from Underneath
While unscrewing the bolt from the inside of the tank, hold the nut underneath the tank with pliers or vise grips. This will prevent the entire assembly from spinning and may help you to loosen the bolt.
Step 5: Cutting the Bolts (If Necessary)
If the bolts still won’t come loose, you might need to cut them. Use a hacksaw or bolt cutter to carefully cut through the bolts. Be very careful not to damage the toilet. Once cut, you should be able to remove the bolts.
Step 6: Remove the Tank
With the bolts removed, lift the tank off the toilet bowl. Place it on a flat surface covered with a towel or cloth to prevent it from cracking or scratching.
Step 7: Clean the Area
Use a putty knife or wire brush to clean away any remaining rust or debris from where the bolts were located. Wipe the area clean with a cloth.
Step 8: Install New Bolts and Reassemble
Insert new bolts and secure them with washers and nuts. Don’t over-tighten as this can crack the porcelain. Reattach the tank to the toilet bowl and reconnect the water supply. Turn the water back on and check for leaks.
Conclusion
Removing rusted toilet tank bolts might require some patience and elbow grease, but it’s a task that can certainly be accomplished with careful attention and the right tools. Always prioritize safety and take your time to ensure a job well done. If you’re unsure about any of the steps or encounter unexpected issues, don’t hesitate to contact a professional plumber.
